Abstract
Influence of sintering time and quenching in Bi2 -x Pb x Ca2Sr2Cu3O y (x=0.0, 0.1, 0.2, 0.25, 0.3 and 0.4) samples have been studied by resistance and XRD measurements. In samples sintered at 850°C for 4 days, T c(0) increases with Pb concentration. T c(0) increased from 81 K for x=0.0 to 109 K in x=0.30 sample and then decreased. Increasing the sintering time to 10 days decreased the T c Quenching further decreased the T c(0). From X-ray diffraction patterns, the intensity peaks of low and high T c phases have been measured. The addition of Pb promotes high T c-phase. Sintering time, slow cooling and rapid quenching studies show that there is an optimum sintering time and cooling rate to produce a high T c-phase.
